Traceable Hi-Accuracy 0.01° Refrigerator Thermometer 4239

New high-accuracy dual thermometer, reads to 0.01 degrees while monitoring temperatures in refrigerator and freezer simultaneously or two refrigerator locations. Temperature-buffered bottle sensor insulates and eliminates rapid temperature changes when refrigerator door is opened. Patented unit fulfils all CDC thermometer and vaccine thermometer requirements. May also be used in water baths, heating blocks, and incubators. Includes two bottle probes.

Guaranteed accuracy set by the National Institute of Standards and Technology.

Records time and date for MIN/MAX readings and hi/lo alarm alerts.
Triple display simultaneously shows minimum/maximum and current temperatures. Minimum/maximum monitors readings overnight, on weekends, or for any time period and displays the exact time and date when the MIN/MAX temperature occurred for both bottle probes. Two channel alarms provide unique visual (LEDs) and audio alerts when temperature rises above or falls below high and low set points. Unit displays the exact time and date when dual thermometer alarms are triggered. Alarms are programmable in 0.1° increments. Visual and audible alarms signal continuously (for days) even if temperature returns to non-alarm range. Ten-foot micro-cable permits refrigerator doors to close on it.

One button user calibration
Range is –58 to 158°F and –50 to 70°C with a resolution of 0.01° and accuracy of ±0.3°C. Probe is sealed in a miniature bottle (1 x 2-1/2 inches) filled with nontoxic glycol. Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration). Eliminates concerns about incidental contact with food or drinking water. First thermometer ever designed to permit one button user-calibration.

Traceable to NIST for accuracy
To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).
